This invention relates to improvements in closures,cand refersparticularly to closures for botties, jars and the like.

Itis an object `of the invention Vto provide a closure including aretaining member which` is split and has the adjacent extremities of thesplit portions and an arm'all held together by a friable joint, eitherwelded, brazed or soldered, so that when the connection is broken theclosure may be readily removed.

Another object of the invention is to provide such a closure wherein thearm is so secured that by movement of it the friable connection may beeasily broken.

Having thus briefly and broadly stated some of the objects andadvantages of the invention I will now proceed to describe it in detailwith the aid of the accompanying drawing in which:

Figure 1 illustrates a plan view of one form of the closure, and

Figure 2 is a section on the line 2--2 of Figf of the invention andFigure 6 is a section on the line 6-6 of Figure 5.

Figures 'I and 8 are details showing two slightly different forms of thefriable joint.

Referring iirst to Figures 1 and 2, IIl designates the neck of aconventional bottle over the mouth of which a circular gasket II isarranged. This gasket is held in position by a split retaining member I2which is circular and has a peripheral depending skirt I3 which iscrimped to engage the periphery of the bottle neck. The member I 2 issplit substantially radially from adjacent one side of the skirt I3across the said member and down to the bottom of the opposite side ofthe skirt, and the adjacent extremities of the split member and skirtportion are arranged in overlapping relation as shown at I 4. Betweenthe overlapping extremities of the member I2 an arm I5 is inserted whichis connected, preferably adjacent the severed skirt side of the member,to both extremities of the latter by a friable connection as indicatedat I6 in Figures 1 and 7. This arm I5 extends across the top of the capto form a lever rigid in the plane of the surfaces of the split memberso that by its movement about the connection I6 in a direction parallelwith the plane of the overlapping extremities the said connection may bereadily broken and the overlapping extremities of the member I2 releasedfrom one another, after which, obviously, the said member and its skirtmay be readily removed.

In the modificationshown in Figures 3 and 4, the periphery I Ib of thegasket I Ia is downturned to extend around the bottle neck Ill, andaring II, made of rubberor other suitable material, is supported by theinwardly exed margin of the gasket periphery. The split retainingmember. I2c, in this instance, is substantially annular to bear upon thegasket IIa over themouth of the bottle and has its integral downturnedskirt inturned at its lower extremity to engage the lower margin of thegasket periphery IIb. In this instance again the member I2a and skirt43a are substantially radially split, the split portion extending fromthe bottom of one side of the skirt I 3a completely across that side ofretaining member I2a and at least partly across its opposite side towardthe other side of the skirt. The split extremities Illa are againarranged in overlapping relation, and between these overlapping portionsan arm I5a rigid in the plane of the surfaces of the overlappingextremities is inserted which is secured to both extremities of themember I2a by a friable connection I6. Thus the connection may bereadily ruptured by movement of the arm |511I in a direction parallelwith the plane of the overlapping extremities.

In the modication shown in Figures 5 and 6, the cap I I c, which extendsover the mouth of the bottle I0, has its periphery downturned to supporta suitable ring I'Ia which bears against a bead Illa. formed around thebottle neck and the top of the cap is spaced above the top of the bottleneck. Around the latter a second and lower flange Illb is providedbetween which and the underside of the downturned gasket periphery asubstantially annular retaining member I 2c is provided. This member istransversely Y split and has overlapping extremities I4c which,

together with an arm I5c rigid in the plane of the overlappingextremities of the transversely split member, are secured to one anotherby a friable joint Ilc. It will be noted in this instance that the twooverlapping extremities of the member I2C rest against one another andthat the arm |50 bears against the outer of the two overlappingextremities in which case the latter is preferably apertured as shown at20 in Figure 8 so that the friable connection I6c may be made directlybetween the arm I5c and the inner of the two overlapping extremitiesthereby holding the outer extremity between them. Again by movement ofthe arm I c in a direction parallel to the plane of the splitextremities breakage of the connection I 6c may be readily causedthereby rendering the member I2c easily removable. Then the cap llc maybe moved downward and slightly tilted to break the vacuum within thebottle after which the gasket may be readily takenoi. Y y

Obviously the f riable connections shown in Figures 7 and 8 may beinterchangeably employed with any of the closure forms above described.

- the latter, a lever rigid in the plane of the surfaces While in theforegoing the preferred embodi-` ments of the invention have beendescribed and shown, it is understood that furtherl alterations andmodifications may be made thereto provided they fall within the scope ofthe appendedclaims.

What I claim is: c

l. A closure including a covering means 'extending over the mouth of avessel, a split retaining memberhaving overlapping extremities holdingsaid covering means in position, a lever arm rigid in the plane of thesurfaces of the over lapping extremities, a iriable joint securing saidoverlapping extremities and one end of the lever arm to one anotherwhereby upon movement of the Varm in a direction parallel with the planeoi' the overlapping extremities said joint is adapted to be broken andsaid overlapping extremities freed from'one another.A

2. A closure including-a gasket extending over the mouth of a bottle, aretaining member including a depending peripheral'skirt engaging theneck ofethe bottle, said memberholding 'said gasket'in. positiomsaidmember vand skirt being split andi having overlapping extremities,a'lever of the overlapping extremities, and a friable connectionsecuring the lever to both overlapping .extremities W-hereby uponmovement of said lever A lapping extremitiesthe connection is adapted tobe broken.

4( A closure including a gasket extending over the mouth of a bottle, asubstantially annular retaining member over the gasket having adependingperipheral skirt, said skirt engaging the neck'of the bottle, said skirtbeing substantially radially split from one peripheral margin and saidsplit extending at least across the adjacent side of the annularretaining member, the adjacent extremities of the latter and of theskirt lying in overlapping relation, a lever arm rigid in the plane ofthe overlapping Vextremities of the skirt, and a friable connectionsecuring the arm to' the overlapping. extremities of the skirt wherebywhen said leverarm 'is sufficiently moved in a direction parallel withthe plane ofthe overlapping extremities the connection is ruptured.
